How do I get a sound file's total time in Java?

Question

--UPDATE

Looks like this code does de work: long audioFileLength = audioFile.length();

    recordedTimeInSec = audioFileLength / (frameSize * frameRate);

I know how to get the file length, but I'm not finding how to get the sound file's frame rate and frame size... Any idea or link?

-- UPDATE

One more working code (using @mdma's hints):

    AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file);
    AudioFormat format = audioInputStream.getFormat();
    long audioFileLength = file.length();
    int frameSize = format.getFrameSize();
    float frameRate = format.getFrameRate();
    float durationInSeconds = (audioFileLength / (frameSize * frameRate));

Which jar file are you using for this? – Umang Kothari Dec 05 '14 at 12:46 — Umang Kothari, Dec 05 '14 at 12:46

Given a File you can write

File file = ...;
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file);
AudioFormat format = audioInputStream.getFormat();
long frames = audioInputStream.getFrameLength();
double durationInSeconds = (frames+0.0) / format.getFrameRate();

I don't what's wrong, but with a file of 18 seconds your code produce a result 149120 while the new code I posted in the question produce 18.64275 (the correct size in seconds). Anyway, I wouldn't have done this without the hints, thanks! – The Student Jun 10 '10 at 15:17

This is a easy way:

FileInputStream fileInputStream = null;
long duration = 0;

try {
    fileInputStream = new FileInputStream(pathToFile);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}

try {
    duration = Objects.requireNonNull(fileInputStream).getChannel().size() / 128;
} catch (IOException e) {
    e.printStackTrace();
}
System.out.println(duration)
